DETAILED DESCRIPTION

An electronic presentation (e.g., a shared screen) may include confidential or sensitive information or content that should be restricted and viewed only by those attendees having the proper permission or credentials. In some situations, the presenter is not the person sharing the screen as this task may be delegated to an assistant, and the assistant may not have the proper permission or credentials to view all of the content in the presentation and on the screen. As such, there may be a need for the ability to share content for an electronic presentation where certain participants (and even the screen sharer) are unable to view all of the content on the sharer's screen.

Some systems may allow the presenter to decide which attendees can view particular portions of the screen being shared, but they may not allow the screen sharer to share content that the screen sharer is unable to view and they also may not ensure that the presenter's authorization decisions are compliant with various organizational standards. Thus, there may be a need for a screen content management system and/or methods for determining viewable screen content to make decisions about which content or resources in an application or presentation are visible to certain users attempting to access or view the content (e.g., via a screen sharing application).

Participants may be in an online meeting hosted on an application server and each piece of content displayed may have a unique identification code (UIC) or number associated with it. The UIC may be referenced by a centralized authorization server (e.g., in an enterprise environment) which may also be referred as an identity management server or resource management server. When the presenter or screen sharer displays content on the screen, each piece of content may be polled against a centralized authorization server to determine whether the participant attempting to view that content has the authorization to view it.

Using the techniques and features described in the present disclosure, an author may assign viewing requirements for each piece of content or resource individually and, upon request to view the content, viewing requirements for each piece of content may be processed individually at the central authorization server to determine whether the content will be visible on each end user's screen. This is processing may be performed by the centralized authorization server that stores viewing requirements/definitions for the content and user details.

In an embodiment, video or content/resource data may be transmitted through an application server (e.g., a screen sharing application host server) which may transmit the video or content/resource data to computing systems of meeting participants. Once data is at the participant's computing system, the application (e.g., screen sharing application) may transmit a series of requests to the centralized authorization server asking if the user running the application has access to view the content/resources that were sent by the screen sharing application. Based on the results from the centralized authorization server, the screen sharing application at the participant's computer system may generate a screen that displays or does not display various pieces of content on the screen, depending on whether the participant has access to view the content/resource.

Referring to the drawings, FIG. 1 depicts a block diagram of a screen content management system 102 in a presentation environment 100, in accordance with embodiments of the present disclosure. Embodiments of the screen content management system 102 may determine which content can be viewed by various users attempting to access or view the content in the presentation environment 100. The various computer systems shown in FIG. 1, including screen content management system 102, may be similar to and/or include similar components to the computer system of FIG. 5. In embodiments, screen content management system 102 may be a central authorization server or centralized authorization server as described herein. The terms central authorization server and centralized authorization server have the same meaning and may be used interchangeably in the present disclosure.

In an embodiment, the central authorization server may integrate with an existing authorization server that an enterprise or organization may have. For example, a centralized identity management server may include details about every employee or user at an enterprise or organization including group membership, employee level, user name, etc.

Screen content management system 102 may be in communication with a network 104 and/or the Internet through which screen content management system 102 may communicate with various other computer systems and machines. For example, screen content management system 102 may communicate with an author computer system 106, a screen sharing application host server or computer system 108, and various user computer systems 110 a . . . 110 n.

Screen content management system 102 may include resource module 112, in accordance with embodiments of the present disclosure. A “module” may refer to a hardware based module, software based module or a module may be a combination of hardware and software. Embodiments of hardware based modules may include self-contained components such as chipsets, specialized circuitry and one or more memory devices, while a software-based module may be part of a program code or linked to the program code containing specific programmed instructions, which may be loaded in the memory device of the computer system 102. A module (whether hardware, software, or a combination thereof) may be designed to implement or execute one or more particular functions, routines, or operations, such as those shown in the blocks of FIG. 2.

Embodiments of the resource module 112 may include one or more components of hardware and/or software program code for receiving registration indications to register content, registering the content as a private resource, assigning a unique identification code (UIC) to the private resource, receiving a viewing requirement for the private resource, and creating and/or modifying a viewing definition for the private resource. Further, embodiments of the resource module 112 may create, store and organize resource profiles and/or definitions and may store data received by the computer system 102 from computer systems 106, 108, and/or 110 a-110 n, by associating the data with one or more fields. The resource module 112 may create, store, and maintain profiles for users of the computing systems 106, 108, and/or 110 a-110 n and/or the presentation environment 100 and/or may register identifying information about users of the 106, 108, and/or 110 a-110 n as well as coworkers, clients, business contacts, and the like, who may frequently attend electronic presentations in the presentation environment 100. For instance, offices or business equipped with a presentation environment 100 and/or screen content management system 102 may obtain personalized information (e.g., employee level or rank, etc.) of presentation authors, presenters, presentation sharers, and presentation invitees and attendees.

Screen content management system 102 may also include a request module 114. Embodiments of the request module 114 may refer to configurations of hardware, software program code, or combinations of hardware and software programs, capable of receiving requests to display private resources, determining whether private resources can be displayed for certain users based on corresponding user information, and transmitting display indications and block indications for private resources. Embodiments of the request module 114 may receive and store data from computer systems 106, 108, and/or 110 a-110 n. In further embodiments, the request module 114 may receive requests to display private resources and associated user information, compare the user information with viewing definitions corresponding to the private resources, determine if the private resources are displayable based on the viewing definitions and the user information, and transmit display or block indications for the private resources to one or more of user computing systems 110 a-110 n (users of which may be viewing a corresponding presentation).

Referring now to FIG. 2, a flow chart of a process 200 for determining viewable screen content, in accordance with embodiments of the present disclosure, is shown. One embodiment of a process 200 or algorithm that may be implemented for determining viewable screen content in accordance with the screen content management system 102 for presentation environment 100 described in FIG. 1 may use one or more computer systems as defined generically in FIG. 5, and more specifically by the embodiments of FIG. 1. Further, process 200 may run on or be executed by a central authorization server which may be similar to screen content management system 102 and may be part of or may use portions of resource module 112 and/or request module 114.

Embodiments of the process 200 for determining viewable screen content may include operations or steps 202-226 (among other operations not shown) as shown in FIG. 2. In an embodiment, process 200 may receive 202 (e.g., at a processor, computer system, or central authorization server) a registration indication to register content as a private resource. Referring now also to FIG. 3, an example presentation screen 300 is shown. Presentation screen 300 may be generated at, for example, author computer system 106. Author computer system 106 may be used by an author or creator of a presentation 302. The author may create one or more pieces or content including, for example, text boxes 304 and 306 and graph 308.

One or more of text boxes 304 and 306 and graph 308 may include sensitive and/or confidential information that should be restricted and viewed only by users having proper permission or credentials for viewing the information. For example, an entity may have multiple levels of employees including executives, directors, engineers, and assistants (among others). Executives may be the highest level in terms of ability/permission to view sensitive information. Directors may be able to view more sensitive information than engineers or assistants, but less than executives. Engineers may be able to view more sensitive information that assistants, but less than executives and directors. Assistants may be able to view the least amount of sensitive information.

The author may include information in text box 304 that is viewable only by executives, directors, and engineers but not assistants. Further, the author may include information in text box 306 that is viewable only by executives but not directors, engineers, or assistants. Additionally, the author may include information in graph 308 that is viewable by executives and directors, but not by engineers or assistants. Thus, the author may wish to give an electronic presentation in which various pieces of content of presentation 302 can be viewed only by those with the proper permissions or credentials, as described above.

Continuing with the above example, as the author creates presentation 302, the author may wish to send registration indications associated with various pieces content in presentation 302 in order to register the pieces of content as private resources. For example, as the author creates text box 304, the author may right-click on text box 304 and make a selection to register text box 304 as a private resource. In response, author computer system 106 may transmit a registration indication associated with text box 304 (e.g., a message or communication) to the central authorization server (e.g., screen content management system 102) over network 104 or the Internet. In this way, process 200 may receive 202 the registration indication to register content (e.g., text box 304) as a private resource at, for example, the central authorization server or screen content management system 102. It should be noted that right-clicking on content is provided as an example action usable by the author to select content to register as a private resource and is discussed for illustrative purposes only. Various user interfaces and other actions usable by the author to select content including, but not limited to, highlighting, dragging and dropping, speech commands, and item browsing/menu selection of items or content as private resources.

Further, process 200 may register 204 the content (e.g., text box 304) as a private resource. This may include creating a record of the private resource (e.g., via resource module 112) or an entry in a database associated with the private resource. Process 200 may assign 206 a unique identification code (UIC) to text box 304 once it is registered as a private resource or as part of the registration process. As shown in FIG. 3 for illustrative purposes only, text box 304 may be assigned UIC 310 (i.e., “01”) which may be stored in connection with a private resource entry associated text box 304 (e.g., at data repository 116).

Process 200 may also receive 208 a viewing requirement for the private resource (e.g., text box 304). The viewing requirement may be indicated by the author (e.g., by right clicking on the content and selecting from a drop down menu, etc.) and may include an employee level, group, or employee-specific or user-specific information representative of who can view the content/resource. The viewing requirement associated with text box 304 may be transmitted to the central authorization server (e.g., screen content management system 102) over network 104 or the Internet. For example, the viewing requirement for text box 304 may be engineer level or greater. Thus, those employees with an employee level of engineer or greater (e.g., engineer, director, and executive but not assistant) may view the private resource (e.g., text box 304).

Continuing with the example above, the author may also have registered text box 306 and graph 308 as private resources and those resources may be assigned UICs in a manner similar to that of text box 304, as described above. The viewing requirement for text box 306 may be executive level (e.g., executive but not director, engineer or assistant) and the viewing requirement for graph 308 may be director level or greater (e.g., director and executive but not engineer or assistant).

Process 200 may create or modify 210 a viewing definition for the private resource based on the viewing requirement. The viewing definition may be part of the record of the private resource (e.g., created via resource module 112) or an entry in a database associated with the private resource. For example, viewing definitions for private resources such as text boxes 304 and 306 and graph 308 may be associated with UICs 310, 312, and 314, respectively, corresponding to text boxes 304 and 306 and graph 308, respectively, as indicated in FIG. 3. The records, entries, UICs, and viewing definitions for the private resources may be created and managed by resource module 112 and stored at data repository 116. Thus, the viewing definition for text box 304 may reflect engineer or greater, the viewing definition for text box 306 may reflect executive, and the viewing definition for graph 308 may reflect director or greater, when referred to by process 200.

The author may complete the presentation 302 and may wish to display the presentation to various users in the presentation environment 100. Users of computer systems 110 a . . . 110 n may attempt to access or view the presentation. In an embodiment, a screen sharing application host or computer system 108 may be used to deploy the presentation 302 over network 104 and/or the Internet such that presentation 302 is viewable by users of computer systems 110 a . . . 110 n. Referring now to FIG. 4, example screens of computer systems 110 a . . . 110 n corresponding to presentation 302 are shown.

Computer systems 110 a . . . 110 n may use a runtime application or environment to view presentation 302, which may be shared over network 104 or the Internet using a screen sharing application and/or screen sharing application host server. In embodiments, the screen sharing application host server may or may not be separate from the central authorization server or computing system 102. In embodiments, a screen sharing application may be run from either a separate screen sharing application host server or from the central authorization server. Further, in embodiments, a separate screen sharing application may not be necessary and the presentation may be deployed directly from the author or sharer's computer system to one or more of computer systems 110 a . . . 110 n over network 104 and/or the Internet. The screen sharing application may interact with the central authorization server to send and receive information, messages, requests, etc., as described herein.

Users of computer systems 110 a . . . 110 n may attempt to view the presentation using the runtime application or environment (e.g., the screen sharing application). The run time application may request to display various private resources. The request may be to computer system 102 or the central authorization server and may include user information about the user of computer systems 110 a . . . 110 n. Process 200 may receive 212 the request to display a private resource and the request may be associated with or include user information (e.g., employee level of the user, a group of the user, a user identification, or other user-specific information).

Request module 114 may handle requests to display private resources. Process 200 may, with use of request module 114, determine 214 whether the private resource is displayable based on the viewing definition of the private resource and the user information. For example, and referring now to FIG. 4, the author of presentation 302 may delegate sharing of the presentation to his or her assistant. The assistant may use computer system 110 a to share the presentation. As the assistant attempts to view or access presentation 302 in the runtime environment (which may be the screen sharing application), the runtime environment may request (e.g., from the central authorization server or computer system 102) to display various private resources of presentation 302. The request may be sent with user information about the assistant (e.g., indicating that the user is an assistant).

Process 200 may receive the requests and corresponding user information and determine whether the private resources of presentation 302 are displayable to the assistant. For example, process 200 may compare the viewing definitions corresponding to text boxes 304 and 306 and graph 308 with the user information corresponding to the user to determine whether text boxes 304 and 306 and graph 308 are displayable to the assistant. Because the viewing definition of text box 304 is engineer or greater, text box 304 is not displayable to the assistant. Because the viewing definition of text box 306 is executive, text box 306 is not displayable to the assistant. Because the viewing definition of graph 308 is director or greater, graph 308 is not displayable to the assistant. Thus, none of the private resources of presentation 302 are displayable to the assistant on computer system 110 a.

Accordingly, in response to determining that the private resource is not displayable based on the viewing definition of the private resource (e.g., text boxes 304 and 306 and graph 308) and the user information (e.g., assistant level), process 200 may transmit 222 one or more block indications from the central authorization server (e.g., computer system 102) to a device associated with the request (e.g., computer system 110 a of the assistant). The block indications may be received 224 from the central authorization server (e.g., computer system 102) at the device (e.g., computer system 110 a of the assistant). The runtime application of the device (e.g., (e.g., computer system 110 a of the assistant) may generate 226 a screen at the device from which the one or more private resources are not viewable.

As a result, as shown in FIG. 4, text boxes 304 and 306 and graph 308 are not viewable by the assistant on computer system 110 a and may be hashed-out, greyed-out, or not displayed at all by the runtime application of computer system 110 a. In this way, the techniques and features of the present disclosure may allow for a system where content being shared or that exists in a shared environment that can be shared or presented by a user (e.g., the assistant) who does not have access to view the content. In other words, the assistant may simply use computer system 110 a to serve (in part) or send the content to the screen sharing application host or to attendees of the presentation so that the actual presenter does not have to be burdened with sharing his or her screen. The assistant may move the shared screen from one portion of the presentation to another upon instruction or timing from the presenter without actually viewing the content. For example, the assistant may be sharing sensitive financial data on the screen without viewing the sensitive financial data itself.

Further, an engineer may use computer system 110 d to view the presentation. As the engineer attempts to view or access presentation 302 in the runtime environment of computer system 110 d (which may be a screen sharing application), the runtime environment may request (e.g., from the central authorization server or computer system 102) to display various private resources of presentation 302. The request may be sent with user information about the engineer (e.g., indicating that the user is an engineer).

Process 200 may receive the requests and corresponding user information and determine whether the private resources of presentation 302 are displayable to the engineer. For example, process 200 may compare the viewing definitions corresponding to text boxes 304 and 306 and graph 308 with the user information corresponding to the user to determine whether text boxes 304 and 306 and graph 308 are displayable to the engineer. Because the viewing definition of text box 304 is engineer or greater, text box 304 is displayable to the engineer. Because the viewing definition of text box 306 is executive, text box 306 is not displayable to the engineer. Because the viewing definition of graph 308 is director or greater, graph 308 is not displayable to the engineer. Thus, of the private resources of presentation 302, only text box 304 is displayable to the engineer on computer system 110 d.

Accordingly, in response to determining that the private resource is displayable based on the viewing definition of the private resource (e.g., text box 304) and the user information (e.g., engineer level), process 200 may transmit 216 a display indication from the central authorization server (e.g., computer system 102) to a device associated with the request (e.g., computer system 110 d of the engineer). The display indication may be received 218 from the central authorization server (e.g., computer system 102) at the device (e.g., computer system 110 d of the engineer). The runtime application of the device (e.g., computer system 110 d of the engineer) may generate 220 a screen at the device from which the private resource is viewable.

Additionally, in response to determining that the private resources are not displayable based on the viewing definition of the private resource (e.g., text box 306 and graph 308) and the user information (e.g., engineer level), process 200 may transmit 222 one or more block indications from the central authorization server (e.g., computer system 102) to a device associated with the request (e.g., computer system 110 d of the engineer). The block indications may be received 224 from the central authorization server (e.g., computer system 102) at the device (e.g., computer system 110 d of the engineer). The runtime application of the device (e.g., computer system 110 d of the engineer) may generate 226 a screen at the device from which the one or more private resources are not viewable.

As a result, as shown in FIG. 4, text box 304 is viewable and text box 306 and graph 308 are not viewable by the engineer on computer system 110 d. Text box 306 and graph 308 may be hashed-out, greyed-out, or not displayed at all by the runtime application of computer system 110 d.

Also, a director may use computer system 110 c to view the presentation. As the director attempts to view or access presentation 302 in the runtime environment of computer system 110 c (which may be a screen sharing application), the runtime environment may request (e.g., from the central authorization server or computer system 102) to display various private resources of presentation 302. The request may be sent with user information about the director (e.g., indicating that the user is a director).

Process 200 may receive the requests and corresponding user information and determine whether the private resources of presentation 302 are displayable to the director. For example, process 200 may compare the viewing definitions corresponding to text boxes 304 and 306 and graph 308 with the user information corresponding to the user to determine whether text boxes 304 and 306 and graph 308 are displayable to the director. Because the viewing definition of text box 304 is engineer or greater, text box 304 is displayable to the director. Because the viewing definition of text box 306 is executive, text box 306 is not displayable to the director. Because the viewing definition of graph 308 is director or greater, graph 308 is displayable to the director. Thus, of the private resources of presentation 302, text box 304 and graph 308 are displayable to the director on computer system 110 c while text box 306 is not.

Accordingly, in response to determining that the private resources are displayable based on the viewing definition of the private resource (e.g., text box 304 and graph 308) and the user information (e.g., director level), process 200 may transmit 216 a display indication from the central authorization server (e.g., computer system 102) to a device associated with the request (e.g., computer system 110 c of the director). The display indication may be received 218 from the central authorization server (e.g., computer system 102) at the device (e.g., computer system 110 c of the director). The runtime application of the device (e.g., computer system 110 c of the director) may generate 220 a screen at the device from which the private resource is viewable.

Additionally, in response to determining that the private resource is not displayable based on the viewing definition of the private resource (e.g., text box 306) and the user information (e.g., director level), process 200 may transmit 222 a block indication from the central authorization server (e.g., computer system 102) to a device associated with the request (e.g., computer system 110 c of the director). The block indication may be received 224 from the central authorization server (e.g., computer system 102) at the device (e.g., computer system 110 c of the director). The runtime application of the device (e.g., computer system 110 c of the director) may generate 226 a screen at the device from which the private resource is not viewable.

As a result, as shown in FIG. 4, text box 304 and graph 308 are viewable and text box 306 and is not viewable by the director on computer system 110 c. Text box 306 may be hashed-out, greyed-out, or not displayed at all by the runtime application of computer system 110 c.

Moreover, an executive may use computer system 110 b to view the presentation and may use a screen of computer system 110 b for reference while giving or moderating the presentation. As the executive attempts to view or access presentation 302 in the runtime environment of computer system 110 b (which may be a screen sharing application), the runtime environment may request (e.g., from the central authorization server or computer system 102) to display various private resources of presentation 302. The request may be sent with user information about the executive (e.g., indicating that the user is an executive).

Process 200 may receive the requests and corresponding user information and determine whether the private resources of presentation 302 are displayable to the executive. For example, process 200 may compare the viewing definitions corresponding to text boxes 304 and 306 and graph 308 with the user information corresponding to the user to determine whether text boxes 304 and 306 and graph 308 are displayable to the executive. Because the viewing definition of text box 304 is engineer or greater, text box 304 is displayable to the executive. Because the viewing definition of text box 306 is executive, text box 306 is displayable to the director. Because the viewing definition of graph 308 is director or greater, graph 308 is displayable to the executive. Thus, of the private resources of presentation 302, text boxes 304 and 306 and graph 308 are displayable to the executive on computer system 110 b.

Accordingly, in response to determining that the private resources are displayable based on the viewing definition of the private resources (e.g., text boxes 304 and 306 and graph 308) and the user information (e.g., executive level), process 200 may transmit 216 a display indication from the central authorization server (e.g., computer system 102) to a device associated with the request (e.g., computer system 110 b of the executive). The display indication may be received 218 from the central authorization server (e.g., computer system 102) at the device (e.g., computer system 110 b of the executive). The runtime application of the device (e.g., computer system 110 b of executive) may generate 220 a screen at the device from which the private resources are viewable. As a result, as shown in FIG. 4, text boxes 304 and 306 and graph 308 are viewable by the executive on computer system 110 b.

It should be noted that while the content and private resources described in the examples shown in the present disclosure are text boxes and graphs, this content is described for illustrative purposes only and is not intended to be a limitation of the present disclosure. The techniques and features described in the present disclosure for screen content management may be applied to any files, text, images, video, audio, documents, screen portions, user interfaces or other content presentable in the presentation environment described in the present disclosure.

Further, while the viewing requirements and definitions discussed in the present disclosure have been with regard to user or employee levels (e.g., executive, director, engineer, assistant, etc.), this is for illustrative purposes only and not intended to be a limitation of the present disclosure. For example, the viewing requirements and definitions may include user groups (e.g., committees, departments, project members, teams, etc.) or specific user identifications such as user names, email addresses, or even names of users or employees.

Additionally, while the present disclosure has been discussed with regard to a screen sharing application, this is not intended to be a limitation of the present disclosure. Another application, such as a word-processing application, presentation creating application, spreadsheet application, CAD application, or any other application which may be used to create content can interact with the central authorization server to register content as private resources, create viewing definitions for the content, and display or block private resources at a user's computer system. For example, an author may create a presentation in which one slide is only viewable by executives, and the author may send that slide to other users to view locally outside of a screen sharing application. The presentation application used to create/view the software may itself communicate, from another user's computer system, to the central authorization server to determine whether to display or block private resources at the user's computer system based on whether that user is an executive, as described in process 200.

In an implementation, when an application (e.g., a screen sharing application, word-processing application, presentation creating application, spreadsheet application, CAD application, or any other application which may be used to create content) is run locally on a computer system, its runtime environment may register each piece of available content that is unregistered with the centralized authorization server as a private resource. The centralized authorization server may assign each private resource a UIC and the private resources may be “owned” by the end-user who initiated the process. The application end-user may define a list of users or user groups who are authorized to view the private resources on an individual basis. Content which is already registered at the centralized authorization server may not be assigned new UICs, but their viewing requirements/definitions may be loaded, updated/modified, or determined (e.g., via the centralized authorization server) and their accessibility or displayability to a user may be determined at runtime.

FIG. 5 illustrates a block diagram of a computer system 500 that may be included in the system (e.g., as computer system 102 or a central authorization server) of FIG. 1 and for implementing the method or process of FIG. 2 in accordance with the embodiments of the present disclosure.

It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present disclosure are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based email). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.

Referring now to FIG. 6, illustrative cloud computing environment 50 is depicted. As shown, cloud computing environment 50 includes one or more cloud computing nodes 10 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 54A, desktop computer 54B, laptop computer 54C, and/or automobile computer system 54N may communicate. Nodes 10 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 50 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 54A, 54B, 54C and 54N shown in FIG. 6 are intended to be illustrative only and that computing nodes 10 and cloud computing environment 50 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

Referring now to FIG. 7, a set of functional abstraction layers provided by cloud computing environment 50 (see FIG. 6) is shown. It should be understood in advance that the components, layers, and functions shown in FIG. 7 are intended to be illustrative only and embodiments of the present disclosure are not limited thereto.

Metering and Pricing 82 provide cost tracking as resources are utilized within the cloud computing environment, and billing or invoicing for consumption of these resources. In one example, these resources may include application software licenses. Security provides identity verification for cloud consumers and tasks, as well as protection for data and other resources. User portal 83 provides access to the cloud computing environment for consumers and system administrators. Service level management 84 provides cloud computing resource allocation and management such that required service levels are met. Service Level Agreement (SLA) planning and fulfillment 85 provide pre-arrangement for, and procurement of, cloud computing resources for which a future requirement is anticipated in accordance with an SLA.
